What is the spring constant for the spring?

AI Thread Summary
The discussion revolves around calculating the spring constant for a spring with a mass of 2.74 kg oscillating at a frequency of 1.972 Hz. The formula used is f = 1/2π * √(k/m), which was rearranged to find k. The initial calculation yielded k = 4.3184 N/m, but the poster doubts its accuracy. Participants suggest re-evaluating the calculation for potential errors and clarify the definition of Hertz. The conversation emphasizes the importance of careful calculation in physics problems.

Homework Statement


A mass 2.74 kg is hung from a spring. The mass is pulled down a short distance and released, it oscillates with a frequency f = 1.972 Hz.

What is the spring constant for the spring?

Homework Equations


f=1/2pi*sqrt(k/m)

The Attempt at a Solution


1.972 = 1/2pi*sqrt(k/2.74)
Rearranged:
k = (1.972/ 1/2pi)^2 x 2.74
= 4.3184 N/m

But this answer is wrong? Can someone please show me how this is so? Thank you

Redo your calculation a bit more carefully.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
